Abstract
A cyhalofop-butyl and fluroxypyr compound herbicide belongs to the technical field of herbicides. The invention provides a compound stem-leaf herbicide for paddy field, which not only can prevent and kill off both gramineous weeds such as semen euphorbiae and broad-leaf weeds in paddy field, but also is safe for rice and does not affect aftercrop. According to the technical key points of the invention, the cyhalofop-butyl fluroxypyr compound herbicide is prepared from the following raw materials and auxiliaries in percentage by mass: 5-10 percent of cyhalofop-butyl, 10-14 percent of fluroxypyr, 10 percent of emulsifying agent 2201-nonyl phenol polyoxyethylene ether, and the balance of dimethylbenzene, which are prepared into emulsifiable solution; or, 5-10 percent of cyhalofop-butyl, 10-14 percent of fluroxypyr, 7 percent of D-425, 2 percent of EFW, 5 percent of ammonium sulfate, 2 percent of polyethylene glycol, and the balance of kaolin, which are prepared into water dispersible granules.
Description
Technical field: the present invention relates to a kind of field weeding agent that is used for crops, is to be used for complex weedicide-cyhalofop-butyl fluroxypyr that stems and leaves of rice is handled.
Technical background: paddy rice is not only the main cereal crops of China, also is one of world's staple food crop.Near in the world half population comprises the population in almost whole East Asia and Southeast Asia, all is food with rice.Production spreads all over each continent except that the South Pole.Eighties of last century late period, about 4,000 hundred million kilograms of world's rice annual production average out to, about 1.45 hundred million hectares of cultivated area.China's rice growing face accounts for 1/4 of national cereal crops, and annual about more than 3,500 ten thousand hectares, output then accounts for over half.No matter cultivated area and output all rank first in China cereal crops.The rice field of all rice workspaces of China always has a large amount of weeds to take place.Medium crop smothering area accounts for more than 46% of total cultivated area, and wherein serious injured area is more than 11.5%, and loss in every year grain is more than 200 hundred million kilograms thus.Therefore, the usage ratio of domestic water herbicides for use in paddy almost reaches 100%, and its dosage is very big.
Along with the development of agricultural cience and farming techniques, one of the applying as the saving of labor, save time of chemical herbicide, cost-effective strong well stimulation.At present, the rice herbicide kind is more, and wherein representative having prevented and kill off the third careless amine, butachlor, dichloro quinolinic acid, the benthiocarb of grassy weed and prevented and kill off broad leaved weed and the bensulfuron-methyl of sedge weed, pyrazosulfuron etc.These weed killer herbicides are sealing weed killer herbicide before the bud substantially, and are undesirable to the weeds effect of having emerged.Paddy field seedling rear defence is few except that the medicament kind of annual weed at present.
The present invention realizes by compound (1) cyhalofop-butyl and compound (2) fluroxypyr compounded combination.
Compound (1) cyhalofop-butyl
Compound (2) fluroxypyr
But find that by Intellectual Property Right Bureau of the RPC's patent retrieval number of patent application is 200910144090.0, publication number is the patent of CN 101590875A, has applied for this two complex compositions.Wherein, the quality percentage composition of cyhalofop-butyl is 5-20%, and the quality percentage composition of fluroxypyr (fluroxypyr) is 15-60%.
And the present invention wherein the quality percentage composition of compound (1) cyhalofop-butyl and compound (2) fluroxypyr be cyhalofop-butyl 5～10%, fluroxypyr 10～14%.The quality percentage composition that is to say fluroxypyr is not 200910144090.0 at number of patent application, and publication number is in the claimed content range of the patent application of CN 101590875A.
Technical problem to be solved by this invention is: can prevent and kill off the paddy field annual gramineous weed after a seedling is provided, can prevent and kill off particularly water peanut of broad leaved weed again, and succession crop not had the cyhalofop-butyl fluroxypyr complex weedicide of influence.Its technical scheme is: cyhalofop-butyl fluroxypyr complex weedicide, it is characterized in that: it is made by the raw material and the auxiliary agent of following quality percentage composition: cyhalofop-butyl 5～10%, fluroxypyr 10～14%, emulsifier 2201-polyoxyethylene nonylphenol ether 10%, dimethylbenzene supplies 100%, is mixed with missible oil; Or cyhalofop-butyl 5～10%, fluroxypyr 10～14%, D-425 7%, EFW 2%, ammonium sulfate 5%, polyethylene glycol 2%, kaolin supply 100%, is mixed with water dispersible granules.
Weed killer herbicide of the present invention has tangible advantage, and it mainly shows:
1, do not have antagonism between weed killer herbicide two components of the present invention, synergistic effect is remarkable.
2, Fa Ming weed killer herbicide compares with using wherein a kind of active ingredient separately, enlarged to kill the grass spectrum, and a weeding, promptly the no weeds of controlled whole growth season joint endanger, and herbicidal effect is remarkable.
3, weed killer herbicide of the present invention is that cauline leaf is handled weed killer herbicide, sees grass back dispenser, and medicine removes to grass, has overcome the blindly defective of dispenser of Herbicidal agent, can be the peasant and reduces unnecessary medication spending.
4, weed killer herbicide effective dose of the present invention is low, a weeding, i.e. and the no weeds harm of controlled whole growth season joint, therefore little to the pollution of environment.
5, weed killer herbicide of the present invention belongs to the low toxicity product, to people, animal, birds and beneficial organism safety, helps keeping ecological balance.
6, weed killer herbicide production technology of the present invention is simple, adopts physical method processing, and three-waste free discharge in the production process has no adverse effects to ecotope.
Its technique effect is: weed killer herbicide of the present invention shows by the field control effectiveness test in 2 years, after Direct-seeding Rice 2-4 leaf phase or rice transplanting are lived, 1～5 leaf phase of weeds, utilize weed killer herbicide 18% cyhalofop-butyl fluroxypyr missible oil dosage 80,100 of the present invention, 120ml/mu, converting water sprays for 40 kilograms/mu, 10,35 days and maturing stage range estimation rice safety and weeds preventive effect, surveyed all preventive effects, result such as following table in 10,35 days:
By range estimation, paddy rice does not see symptom of chemical damage from the dispenser to the maturing stage, to rice safety.The preventive effect of weeds reached more than 85% in 10 days, reached more than 95% in 35 days, and along with the increase of dosage, preventive effect obviously strengthens, at paddy field 80ml/667m
2Can reach good herbicidal effect, a dispenser can be controlled the weeds in the crop whole growing, and second stubble crop is not had influence, is the desirable complex weedicide of present control efficiency.
This patent and number of patent application are 200910144090.0, and publication number is that the patent of CN 101590875A is compared, though content of effective has reduced than it, the preventive effects of weeds are not reduced.80,100ml/667m
2Under the dosage, the quick-acting of this patent is better than it, and 10 days preventive effect is more than 85%, and 35 days preventive effect is also good than its preventive effect of 30 days.Therefore, peasant's drug cost is lower.
